Description
The open-source MPI-AMRVAC software [https://amrvac.org and Keppens et al, A&A 673, A66, 2023] is widely used for numerical plasma-astrophysical research, and has a fair number of offspin codes (BHAC, Gmunu, GR-AMRVAC) that routinely perform up to general relativistic magnetohydrodynamic (MHD) simulations. Its modular design is a key feature of the framework, along with the automated grid-adaptivity (block-based AMR) and its high flexibility for user-defined prescriptions. Here, I will give an overview of the latest applications and code developments that target solar and heliospheric modeling, where Newtonian physics is at play, sometimes enriched with non-thermal particle processes. These include the first realistic models of solar prominence formation, studies of particle acceleration in erupting flux rope settings, self-consistent flare models with energetic particle beams included, global solar coronal models, and heliospheric forecasting using the Icarus user module. Multiple ways to numerically handle the governing MHD equations - including many non-ideal effects - are available and can serve to benchmark the optimal method selection for robust operational purposes. I will end with a preview on the AGILE development, where the same code flexibility will efficiently exploit the most modern hybrid CPU-GPU platforms.
